In an earlier thread ("questions: file systems (was: /var/lib/flatpak/repo/objects...)"), Will referred me to the Redhat website
"https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/9/html-single/managing_file_systems/index#types-of-file-systems_overview-of-available-file-systems";.
I've read that a few times.  I've also examined wikipedia's "Comparison of File Systems":
"https://en.wikipedia.org/wiki/Comparison_of_file_systems";.
It seems the main file systems to consider are BTRFS, ext4, and XFS.  Based on the wikipedia article, I made a table showing how those three choices differ.  Based on that comparison, the Redhat article, and other discussion on this list (including in this thread), I notice a few of you seem to be real fans of BTRFS, and a few of you seem to be quite critical of BTRFS.  I'm currently weakly leaning towards BTRFS for the new desktop (for those things where I have a choice).  I do recognize the choice of file system is a matter of "use case" (broadly speaking) and, more likely than not, personal preference.

Questions:
If I use BTRFS for /home (that's the default, right?), can I easily turn off
* copy-on-write,
* compression,
* encryption, and
* (maybe) data deduplication
for /home, but still easily use those capabilities on a few scattered files and sub-directories within /home?

Am I correct in thinking that all top level directories other than /home must use specific file systems and I should not concern myself with those, but use the defaults?
